Description |
|
|
nSize |
Size of this structure. Used for versioning. |
|
|
nDistance |
Distance from the point, in pixels. This value indicates how close the point must be to an object in order to "hit" the object. |
|
|
dwFlags |
Flag that determines which objects to consider when hit testing. Possible values are: |
|
|

|
VECTOR_HITTEST_CLOSEDFIGURES |
Determine whether the hit test point is inside closed objects. |
|
|
VECTOR_HITTEST_IGNORESELECTED |
Do not test objects that are already selected. |
Comments
LVectorBase::GetHitTest and LVectorBase::SetHitTest get and set the current hit test options. LVectorBase::HitTest actually performs the hit test.
The hit test options must be set before calling LVectorBase::HitTest.
pVECTORHITTEST is a pointer to a VECTORHITTEST structure.
